If your speed increases dramatically, it probably isn't your clutch... Unless you meant engine speed? Look at the RPM gauge next time. Does it shoot up while the car fails to accelerate? If so, clutch... If not, it's something else.

Could be HPFP failure, could be tune.... Are you tuned? Could also be spark plugs, if the computer is pulling timing you'll accelerate in waves (Depending on how much timing is being pulled).
